background: this study evaluated the relation between telomere length in lymph node (ln) and prognosis of esophageal squamous cell carcinoma (escc). materials and methods: lns collected from 50 patients were assessed by pathological examination and quantitative reverse transcription polymerase chain reaction (qrt-pcr), which was used for detecting telomere length. the relation between clinical...

Background: Telomeres are particular sequences of DNA located at the end of the eukaryotic chromosomes that are essential for genome integrity. Telomere length in spermatozoa differs among males, as well as spermatozoa. Also, decreased telomere length in spermatozoa of infertile men is associated with the reduction of fertility potential and embryo quality. Density gradient centrifugation (DGC)...

Background: Telomeres are evolutionary, specialized terminal structures at the ends of eukaryotic chromosomes containing TTAGGG repeats in human. Several human diseases have been known to be associated with dramatic changes in telomere length. The aim of the present study was to assess the correlation between the relative leukocyte telomere length (LTL) and infertility in a group of Iranian azo...
Background & objective: Mesenchymal stem cells (MSCs) are presently isolated from various human tissues such as bone marrow. These cells have relatively high replication potential and can differentiate into various cell lineages with mesodermal and non-mesodermal origin and therefore, show promising in treatment of diseases. Their striking features like availability of source, ease of isolation...
Background Polycystic ovary syndrome (PCOS) is one of the reasons of infertility in women with chronic anovulation. Ovulation process is tightly regulated by molecular mechanisms controlling proliferation/differentiation of cells. Telomeres, TTAGGG tandem repeats, are transcribed into a non coding RNA, named TERRA. Recent studies suggest that TERRA sustain several important functions at chromos...
background: exercise and consumption of green tea affect the aging process. however, the effect of exercise training combined with green tea extract on leukocyte telomere length, quality of life (qol) and body composition in aging has so far been unclear and inconsistent. objective: the aim of the present study was to determine the effectiveness of aerobic training intervention and green tea ex...
Background: Epidemiological studies have probed the correlation between telomere length and the risk of lung cancer, but their findings are inconsistent in this regard. The present meta-analysis study has been carried out to demonstrate the association between relative telomere length in peripheral blood leukocytes and the risk of lung cancer using an established Q-PCR technique. Methods:...
